Abstract
Described is a scintillator screen including a plurality of filaments. Each of the plurality of filaments includes scintillating particles dispersed within a thermoplastic polymer. The thermoplastic polymer includes an elastic additive. The scintillating particles are from about 10 volume percent to about 60 volume percent of each of the plurality of filaments. Each of the plurality of filaments has a refractive index of greater than or equal to 1.5. The plurality of filaments are substantially parallel to each other and are at a volume packing of from about 60 percent to about 90 percent.
Claims11
A scintillator screen comprising:
- a plurality of melt compounded and extruded filaments, wherein each of the plurality of filaments includes prompt emitting phosphor scintillating particles dispersed within a thermoplastic polymer, wherein the thermoplastic polymer includes an elastic additive, wherein the scintillating particles are from about 10 volume percent to about 60 volume percent of each of the plurality of filaments, wherein each of the plurality of filaments has a refractive index of greater than or equal to 1.5, and wherein the plurality of filaments are substantially parallel to each other and at a volume packing of from about 60 percent to about 90 percent.
A scintillator screen comprising:
- a plurality of melt compounded and extruded filaments having a core and a shell surrounding the core, wherein the core of each of the plurality of filaments includes prompt emitting phosphor scintillating particles dispersed within a polymer, wherein the polymer includes a polypropylene and an elastic additive, wherein the scintillating particles are from about 10 volume percent to about 60 volume percent of each of the plurality of filaments, wherein the shell of the plurality of filaments does not include prompt emitting phosphor scintillating particles and has a refractive index of greater than or equal to 1.5, wherein the plurality of filaments have a storage modulus greater than or equal to 1000 dynes/cm2, and wherein the plurality of filaments are substantially parallel to each other at a volume packing of from about 60 percent to about 90 percent.
A scintillator screen comprising:
- a plurality of fibers having a core and a shell surrounding the core, wherein the core of each of the plurality of fibers includes prompt emitting phosphor scintillating particles dispersed within a thermoplastic polyolefin, where the thermoplastic polyolefin includes an elastic additive, where the elastic additive is an alkylene vinyl acetate, wherein the scintillating particles are from about 10 volume percent to about 60 volume percent of each of the plurality of fibers, wherein the shell of the plurality of fibers does not include prompt emitting phosphor scintillating particles and has a refractive index of greater than or equal to 1.5, and wherein the plurality of fibers are substantially parallel to each other at a volume packing of from about 60 percent to about 90 percent.
